Capital gains taxes explained
Capital gains arise when you sell a capital asset — such as stocks, bonds, or real estate — for more than your adjusted basis in the asset. Long-term capital gains — assets held for more than one year — enjoy preferential federal tax rates compared to short-term gains, which are taxed as ordinary income.
The long-term rates currently span 0%, 15%, and 20% based on taxable income and filing status. Understanding how these thresholds work is essential for effective tax planning around asset sales.
Understanding how the 0% capital gains tax rate works
The 0% long-term capital gains tax rate applies when your taxable income (including gains) stays below a specific threshold, and you've held the asset for over a year. Here are the 2026 brackets for the 0% and 15% long-term capital gains rates, according to the IRS:
| Filing Status | Maximum 0% Rate Amount | Maximum 15% Rate Amount |
| Married Filing Jointly | $98,900 | $613,700 |
| Married Filing Separately | $49,450 | $306,850 |
| Head of Household | $66,200 | $579,600 |
| Single | $49,450 | $545,500 |
| Estates and Trusts | $3,300 | $16,250 |
If your income is above these thresholds, that additional amount will be subject to a 20% capital gains tax.
These thresholds mean that if your taxable income, after deductions, is below the "maximum 0%" figure for your filing status, you may pay no federal tax on qualified long-term gains. Timing, deductions, and other sources of income matter just as much as the sale itself.
How the income tax rate is calculated
Your taxable income is realized by subtracting either the standard deduction or itemized deductions (whichever is greater) from your adjusted gross income (AGI).
In 2026, the standard deduction will be $16,100 for single filers and $32,200 for married couples filing jointly. Once deductions are applied, your taxable income determines whether you fall below the 0% capital gains threshold. Planning your asset sales in a year when your taxable income is lower increases your odds of hitting the 0% rate — rather than triggering the 15% or 20% rate.

How the 2026 long-term capital gains tax rates provide investment opportunities
The existence of a 0% rate means you can time certain investment decisions to pay no federal tax on gains — if you meet the income criteria.
Strategic moves might include harvesting gains in a year when income is lower, or offsetting gains with losses to keep taxable income under the threshold. Additionally, holding assets for more than a year unlocks the preferential rate. For savvy investors, this can enhance after-tax returns and allow more capital to stay invested.
Why you might need to coordinate timing and income
Selling appreciated assets in a high-income year could potentially push you past the 0% threshold and trigger taxation at 15% (or higher) on gains.
By contrast, planning the sale for a year with less ordinary income, or increasing deductible expenses, can keep you under the threshold — timing matters. Balancing income, deductions, and investment gains are smart tax strategies that should not be overlooked.
Consider state and other taxes when strategizing
Although federal rates for long-term capital gains are established, your state may impose its own tax on capital gains or treat them as ordinary income.
Additionally, high-net-worth individuals may face the Net Investment Income Tax (NIIT) of 3.8% if their modified adjusted gross income (AGI) exceeds certain thresholds. A plan that maximizes the zero federal rate but ignores state or NIIT implications may still leave you paying more tax than expected, which makes comprehensive financial planning essential.
Hold your assets long enough to qualify
Short-term capital gains — assets sold within one year of acquisition — are taxed at ordinary income tax rates, which for many people may be significantly higher than the long-term gains rates.
By contrast, assets held over one year qualify for the preferential long-term gains rates discussed, including potentially the 0% rate. Understanding your holding period is critical; an impatient sale can mean paying far more tax. Staying invested for the long term often pays off not just in growth, but also in tax efficiency.
Bottom line
By combining smart timing, holding assets long enough, coordinating income, and leveraging deductions or losses, many taxpayers can sell appreciated investments and pay no federal tax under the 0% long-term capital gains rate.
The 2026 thresholds offer a clear target — staying below them can help you retain more of your profits and reinvest with confidence. With thoughtful tax strategy and consistent planning, you can prepare yourself financially for a stronger, more secure future.
